Title: Frequency-selective phase/delay control for an amplifier
Inventor: LEFFEL MICHALE DAVID
IPC: H03F1/32
Filed: 2004-08-16
Abstract: The insertion phase or delay of an amplifier can be controlled by comparing signals from the amplifier path with signals from a corresponding reference path without requiring the overall signal delay though the reference path to nominally match the overall signal delay though the amplifier path. Amplifier and reference path signals can be combined to form a combined signal whose power is detected using a narrow-band, frequency-selective power detector. For given phase and delay offsets between the amplifier and reference paths, cancellation (i.e., perfectly destructive interference) will occur at a series of different frequencies. By operating the power detector at one of these cancellation frequencies, a variable phase or delay adjuster in the amplifier path can be controlled to minimize the detected power level in order to achieve a desired level of insertion phase for the amplifier, without having to implement an expensive delay element in the reference path.

Title: Plastically deforming and radially expanding a tubular member
Inventor: COOK ROBERT LANCE
IPC: E21B43/10
Filed: 2001-09-27
Abstract: A mono-diameter wellbore casing is formed by plastically deforming and radially expanding a first tubular member 155 within a wellbore 10 using an expansion cone 115 with an over-expansion sleeve 130. The over-expansion sleeve 130 may be made of a frangible or elastic material or be composed of arcuate inserts separated by resilient members. After a predetermined time period and/or a predetermined axial displacement of the cone 115, the over-expansion sleeve 130 is forced off the cone 115 due to the frangible or resilient nature of the over-expansion sleeve. Continued movement of the cone 115 expands the tubular member 155 by a lesser amount than that provided by the combination of the over-expansion sleeve 130 and the cone 115. A tubular member 200 is placed in overlapping relationship with the tubular member 155 and plastically deformed and radially expanded to mate with the tubular member 155. An expansion cone 215 is driven downwardly to plastically deform and radially expand the tubular member 200 to form a mono-diameter casing. Other embodiments are described in which the initial expansion is done by an inflatable bladder or a roller expansion device.
